What were your earliest symptoms?

Hey ladies, so I found out I was pregnant when I was only 3 or 4 weeks. Before I found out I peed like crazy, anything I would drink 3 mins later I was in the bathroom. I had the worse back pain, and I was always sick in my stomach. A lot of people say you don't experience the frequent urination until later on but that's not true for me. So what were your eatliest symptoms?😊
